- RADIATOR.

Specification of Letters Patent.

Patented April 6, 1909.

To all whom it may concern.'

Beit known that I, ANDREW C. EDGAR, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Radiators, of which the following is a specification.

The object of my invention is to design a radiator section which can be used either for hot water or steam; the section being made in multiple and each section being an integral casting.

' in the accompanying drawings Figure i, is a perspective view of my improved radiator section are closed by plugs la, h and diator section; Fig. 2, is a vertical sectional view illustrating two of myvradiator sections coupled together for use as a hot Water radiator; Fig. 3is a sectional plan vview on the line 3-3, Fig. 2; Fig. 4:, 1s a sectional plan view on the line 4-4, Fig. 2; Fig. 5, is a vertical sectional view showing my invention adapted for use as a steam radiator andv Fig. 6, is .an inverted sectional plan on the line 6-5, Fig. 5.

Referring in the first instance to Fig. 2, A, A are two sections of a radiator, each having openings a at the top at each end and openings al at the bottom at each end. Each radiator section A is made as shown in cross section, Fig. 3, each'side t of the section A is corrugated as shown, forming prominent ribs and deep grooves between the ribs, and the inner edges of each section are connectedtogether by transverse partitions d; these partitions stop short ofthe top and bottom so as to form connecting channels c at the top and connecting channels c at the bottom, thus while one compartment is separated from another by the partition d the steam or hot Awater is free to' flow from one compartment to the other through the channels c, c.

In Fig. 2, l have shown the radiator sections coupled together by tapered nipples e, e adapted to the openings a, a at top and bottom of each radiator section. The bosses for the reception oi the nipples project partly on the outside of the radiator and partly on the inside, as shown in Fig. 3, so that when the sections are assembled the corrugationsare continuous and the radiator has the appearance of a single casting.y

The sections may be secured together in any suitable manner. In Fig. 2, l have shown a tie rod f having a nut f' at one end,

this rod passes through openings extending from one side of the radiator sections to the other, but these openings do not communicate with the interior of the radiator section. The two radiator sections are cou led at the bottom, in the resent instance y a bolt g passing throng lugs g depending from the radiator sections, but other means of fastening the sections together may be resorted to Without departin from the main feature of the invention. T e radiator sections A, A are supported in the resent instance by the feet B attached te t e sections by bolts b.

The upper outside openings a, a of each ra The hot Water will pass into the irst section of the radiator and at once travel to the top of the radiator section and .through the nipples e, and the cooler water will pass from the lower portions of both radiator sections through the outlets C.

When my invention' is applied as a steam radiator then l attach two radiator sections D, D', one to each side of my improved radia tor section A, either by screw coupling nipples e or other attachments, as shown in Fig. 5; the openings the upper portions of the radiator being closed'by screw plugs h. A steam pipe E having a valve e2 is attached to one end of the radiator and when steam is admitted it iirst fills the section D,then enters the section A iilling this section, and finally enters the end section D g all the openings being at the bottom. This may be a one pipe system, as shown in the drawings, or there may be another pipe coupled to the section D', as shown by dotted lines in Fig. 5, if desired. In this instance the legs B form an integral part of the end sections D, D and there may be as many sections of my improved radiator 'as desired; all the intermedi# ate sections being similar to thatV illustrated at A., F 5- a I l In both hot water and steam the number of sections in the unit will depend upon the area to be' heated.

Thus it will be seen by the above description that I am enabled to construct a radiator section which can beused in a system using either hot Water or steam. When hot loo tion of the steam in the radiator.

water is used the sections are sim ly coupled upin any number as desired and) the Water supply and return either attached to the lower or upper portions of the sections. lVhen steam is used single end sections are used in connection with my improved radiator' section, so asto insure the proper circula- I claim .1. An integral radiator section made of cast metal, both sides of the radiator being corrugated forming vertical ribs with deep channels between them on the inside and outside, vertical, 'solid partitions uniting the inwardly projecting ribs and stopping short ofthe top and bottom of the radiator section to form upper and lower circulating passages.

2. The combination iny a radiator, of two or more sections situated end to end, the side walls of said sections being corrugated forming vertical ribs with deepV channels between them on the inside and outside and having vertical partitions uniting the inwardly proecting ribs and stopping short of the to and ottom to form upper and lower circu ating passages, the corrugations bein so formed that when .the sections arecoup ed together the ribs and channels will be uniform throughout.

In testimony whereof, I have signed my 30 name to this speciiication, in the presence of two subscribing Witnesses.
